Piper PA-31 Cheyenne

The pilot tried to activate the radio-controlled runway boundary lights about 10 miles away, and also while he was in the traffic pattern, but he was unsuccessful. He continued his descent to approximately 500 feet above the ground using the vasi (visual approach slope indicator) lights. The pilot stated that he had the airport in sight and' felt well enough in sight to complete landing.' The airplane touched down in approximately 18 inches of snow 60 feet off the right side of the runway. The pilot reported that there was no mechanical malfunction. He said as he got closer to the ground he realized it was snow-mobile tracks and not the runway. He tried to go-around but the airplane impacted the ground collapsing the nose gear.

Shortly after takeoff from Cologne-Bonn Airport, while in initial climb, the pilot declared an emergency and was cleared to return. While completing a turn, he lost control of the airplane that entered a dive and crashed onto a house located in Lind, less than 2 km south of the airport. The pilot, sole on board, was killed. There were no casualties on the ground.

The pilots had entered into an agreement with the 5 pax to fly them to a ski resort. The airplane owner stated that the pic, who was the company pilot, did not have permission to use the airplane, nor did the owner know the pax. The airport at the ski resort is located in mountainous terrain at 6,750 feet msl. There is no instrument approach. There is no record of any weather briefings. The airplane collided with terrain (Mt Clark) at about 6,580 feet msl approximately 7.5 miles southwest of the destination airport. Weather for the area was: mountains locally obscured 3,000 to 5,000 feet scattered to broken with tops to 9,000, and widely scattered visibilities below 3 miles with snow and rain showers. Examination of the wreckage and impact site revealed the aircraft collided with the brush and snow covered 45° slope in a level left turn. All seven occupants were killed.

The twin engine aircraft departed Salzburg on a charter flight to Altenrhein, St Gallen, carrying five passengers and one pilot. On approach to Altenrhein Airport, the pilot encountered poor weather conditions. Unable to locate the runway due to low visibility, he abandoned the approach, initiated a go-around procedure and was cleared to divert to Friedrichshafen-Bodensee Airport that he reached few minutes later. On final approach, the aircraft stalled and crashed in a field located short of runway threshold. The aircraft was destroyed upon impact and all six occupants were killed. At the time of the accident, weather conditions were poor.

The pilot made routine radio communications in preparation for takeoff. The airplane departed from runway 25 in daylight instrument meteorological conditions (IMC) with light snow and fog. Shortly after takeoff, the airplane's radar target disappeared from the controller's scope. The airplane crashed on wooded terrain about two miles south-southwest of the departure end of runway 25. Impact occurred in an steep, nose down, left wing low attitude. The airplane was destroyed by ground impact forces and a post-impact fire. No physical incapacitation of the pilot-in-command was determined. No contributory mechanical malfunctions of the airplane were discovered. All three occupants were killed.

The flight was level at 10,000 feet msl in IMC conditions when the controller noticed the airplane take a sharp right turn and descend rapidly. Attempts to contact the flight were negative. Examination of the accident showed all the major components present, however, impact damage precluded any flight control continuity check. The engines could not be recovered from the impact crater. The accident site was not accessible with specialized equipment. The pilot, sole on board, was killed.

On final approach, after being cleared to land, the pilot informed the controller that he might have to shut down an engine. He declined to declare an emergency or request assistance. On short final, the aircraft was observed to roll to the left and descent into the terrain. Subsequent examination revealed evidence that the left engine was not developing power, although the left propeller was not feathered. There was evidence that the right engine was producing high power during impact. No mechanical deficiency of the left engine or propeller was found. The pilot, sole on board, was killed.

The pilot noted an over torque condition in the left engine as the aircraft was on an ILS approach. He made a go-around and initiated another approach with the engine shut down. He was unable to maintain altitude and the aircraft began a decent that was not arrested. Subsequently, it crashed into 2 homes, approximately 6 miles from the airport. An exam of the left engine revealed the drive shaft from the fuel pump to the fuel control was sheared at the plastic coupling. Further exam revealed the twin bearings that supported the driveshaft had failed. Also, there was evidence the drive shaft had shifted and subsequently an overtorque condition resulted. All three occupants were killed.

The twin engine airplane departed Ponta Delgada Airport at 1449LT on a survey flight over the Atlantic ocean to trace shoals of tuna, carrying two passengers, one observer and one pilot. At 1751LT, the mission was over and the pilot was cleared to descend to Horta Airport. On final approach to runway 29, after being cleared to land, the aircraft entered a right turn then lost height and crashed 600 meters to the right of the runway 29 extended centerline. The aircraft was totally destroyed and all four occupants were killed.

After takeoff from Tocache Airport, while climbing, the twin engine aircraft exploded and crashed, bursting into flames. Both occupants were killed.
